Rain, rain, don't go away... but

it's been so long I've forgotten how to deal with you. How does Mr T walk to school in the rain? How do I walk to playgroup on the rain? How on earth do I use an umbrella with a stroller? Do little kids use umbrellas or should Little C have some waterproof gear? Do I even own an umbrella?

I'm sure rain was no big deal when Mr T was small and we didn't have a car but I can't remember what we used to do... Where has my rain brain gone?
